James Mason, the Irish-born American was a leading player in the 1870s and 1880s, and one of the better early chess authors, too. He sometimes fell out of his chair because he was so drunk.

American master and Pillsbury second W.E. Napier related his experience of seeing Mason helped into the playing hall and seat because he could not walk on his own, proceed to win in brilliant fashion against a strong opponent, and then stagger off after the game to celebrate at a pub.

Ok, he was not as famous as the players mentioned above but we shouldn't forget gm Valentin Arbakov. A very colorfoul person. He excelled at blitz. I remember seeing him playing in Paris at the Jardin du Luxembourg [a garden in the center of Paris] during the 90s.

I don't know whether he was drunk when he played, nobody submitted him to an alcohol test before starting a game.

But it could explain why he chose to play blitz: "only" a few minutes of intense concentration.

I don't know if they played serious match and/or tnmt games while drunk (or even while under the influence) but Alekhine and Blackburne were apparently serious drinkers at least once during their careers. Alekhine was found drunk in a field prior to one of his World CH match games in 1935, and he's supposed to have dried up totally while preparing for the 1937 rematch.

Spielmann was once offered a job as a chess coach in the USSR which was apparently a good deal (ie good salary and/or good perks) but he declined because Russian beer was not good enough for him.

I enjoy drinking myself but not to excess (usually) so I would urge you to find a sober role model among the many GMs out there available for the position. You can still try to play like Alekhine, Blackburne or whoever but I would highly recommend you attempt to do...while sober!

The late Alexander Wojtkiewicz, a.k.a. "Wojo" was no mean drinker. Shabalov recalled:

Aleks began playing chess at an early age, and by the time I joined the Riga Chess Club at age 7 – Aleks was five years older than me – he had become the strongest and most promising junior in the city. He was always Tal’s favorite student, because of his talent and his obvious affinity to the three required non-chess components of Tal’s chess school: smoking, drinking, and womanizing.
